摘要：
An anti-jamming method based on time-domain jamming cancellation and signal sparse reconstruction is proposed for the problem of “premature explosion" or “misfire" of continuous wave frequency-modulated (FM) fuzes under frequency sweeping jamming. The location and duration of jamming are detected through time-domain outliers, and the abnormal data are eliminated to suppress the impact of the jamming on the fuze. For the signal sparsity caused by jamming cancellation in time domain, an optimization equation for differential frequency signal reconstruction based on sparse regularization terms is established, and an ADMM-based iterative reconstruction algorithm is proposed. The performance of the proposed method is verified by using the simulated and measured data. The results show that the method can be used to suppress the influence of frequency sweeping jamming, accurately obtain the target range-velocity information, and improve the ability of FM fuze to resist the frequencys weeping jamming with a signal-to-noise ratio of –15 dB and a zero sample rate of less than 70%. © 2024 China Ordnance Industry Corporation.
